ENDELL T. CRANE AND EDWARD H. CRANE, OF ODEBOLT, IOWA.

FOLDING UMBRELLA.

To all whom it may concern:

Be it known that we, ENDELL T. CRANE and] EDWARD H. CRANE, citizens ofthe United States, residing at Odebolt, in the county of Sac and Stateof Iowa, have invented certain new and useful Improvements in FoldingUmbrellas, of which the following is a specification.

This invention relates to umbrellas and refers especially to that classof such devices which is known as folding umbrellas.

An object of this invention is to construct an umbrella frame which canbe folded in a few simple operations and which will be locked in an openposition when raised.

Another object of this invention is to construct an umbrella by whichthe stafi can be folded upon itself and so that the ferrule upon the endof the staff may be telescoped in the upper end of the staff to reducethe size of the umbrella to less than one half of its original size.

A further object of this invention is to produce a device of thischaracter that will be simple in construction and in the number of itsparts, durable and easy of manipulation and manufacture.

Other objects and advantages will be apparent from the followingdescription and it will be understood that changes in the specificstructure shown and described may be made within the scope of the claimwithout departing from the spirit of the invention.

In the drawings forming a portion of this specification and in whichlike numerals of reference indicate similar parts in the several views,Figure 1 is a side elevation of the complete device in an open position.Fig. 2 shows the umbrella in side elevation in a closed position. Fig. 3is a detailed and enlarged sectional view of the staff showing thejoints thereof. Fig. 4 is an enlarged and detailed view of one of theribs showing the joint and locking means therefor. Fig. 5 is a crosssection centrally of the lower section of the staff.

Referring now to the drawings, and 11 designate the two sections of thestaff. The section 10 is recessed transversely at its lower end as at 12and carries a depending rod 13 intermediate of the recess which extendsslightly below the extremities of the section 10 where it is curved uponitself to form an eye 14. A. link 15 is secured at one end to the rod 13through the eye 14 and extends Specification of Letters Patent. PatentedSept, 21, 1909,

downwardly where it engages in an eye 16 formed upon the upper extremityof a rod 17. The rod 17 is inclosed by a casing 18 which carries atongue 19 transversely disposed across the upper ends thereof and whichis normally engaged in the recess 12. The casing 18 is provided with asleeve 20 intermediately disposed within the same which is provided witha central angular bore through which the rod 17 is passed. The sleeve 20is secured in the casing by a pin 20. The rod 17 is angularly formedintermediate of its length as at 21 for the purpose of preventingrotation of the same but allowing free vertical reciprocation thereof.The casing 18 is provided with an annular flange 22 which extendsoutwardly and which is fitted into a depressed portion 23 formed in theupper extremity of the section 11. The section 11 is provided with aninwardly extended flange 24: which engages the flange 22 and preventsthe casing '18 from being removed from the section 11 but allowing freerotation of the same. The rod 17 extends below the casing 18 into thesection 11 where it is threaded to engage through the threaded centralopening of a nut 25 which is carried by the section 11. The lowerextremity of the rod 17 extends down into the bottom of the section 11and is headed as at 26, to prevent the rod 17 from being withdrawn fromthe section 11.

The upper extremity of the section 10 is hollowed out to receive thepoint 27 of the staff. In the upper end of the section 10 there is adouble bayonet slot 28 in which a stud 29, which is carried by the point27, is engaged and travels. A notch 30 is disposed upon the upper end ofthe section 10 through which the point 27 is adapted to slide. A spring31 is secured between the lower end of the hollow portion upon a pin 4Adisposed through the section 10 and the under side of the point 27 forthe purpose of raising the point outwardly in the inner and outerpositions. The ribs of the umbrella are provided with apertures at theirupper ends for the purpose of pivoting the same to the notch 30 and toradially extend therefrom. The ribs each comprise two sections 32 and 33which are transversely recessed at their inner ends which are hingedby'the plate 34 through the medium of pins 35 and 36 which are passedthrough the sections 32 and 33 and through the opposite extremities ofthe plate 34 which is fitted into the recesses. The sections 32 and 33are locked in an open position asleeve which is slid ably mounted uponthe rib and is pivotally connected to a runner 38 slidably mounted uponthe staff, by a stretcher 39. The stretcher 39 carries an upwardlyextending arm which is extended outwardly when it engages in a channel41 against an abutment 41-3 formed upon the section 32 of the rib whenthe umbrella is extended to its open position. The arm 10 serves to lockthe sleeve in rigid position directly over the plate 34 preventing theswinging of the section 33. The section 33 carries a leaf spring 12which engages the inner side of the sleeve 37 and serves as an auxiliaryhold for the same.

The operation of the device is as follows: When the umbrella is openedand it is desired to close the same the runner 38 is drawn down thestaff and the arm 10 is disengaged from the channel 411. When thestretcher 39 is disposed at a sufficient angle the sleeve 37 is movedupwardly upon the section 32 to release the plate 34 and allow thesection 33 to be folded up upon the section 32. The section 32 is nowfolded down against the staff and the runner 38 is forced upwardlycarrying the sleeve 37 to the upper portion of the section 32; The point27 is rotated through a slight angle to release the stud 29 from theslot and is then forced against the spring 31 down into the hollowedupper end of the section 10 ofthe stafi where it is again rotated andsecured in that position in the bayonet slot;- The sec tion 11 is nowrotated and the rod 17 is fed upwardly until the tongue 19 can bewithdrawn from engagement with the recess 12 and the section 11 can befolded up upon the section 10-, the link 15 acting as a hinge;

The uinbrella is now folded and ready to be carried or packedfortransportation.

What is claimed isf A stafi for a folding umbrella comprising a sectionhaving a recess in thelower end thereof and a hollowed portion in theupper extremity thereof, a point slidably disposed within said hollowedportion, a spring in said hollowed portion for holding said point inposition, a second section, a casing swiv-' eled in the upper end ofsaid second section, a tongue disposed upon the upper end of said casingfor engagement in .said recess, a linked rod carried by said firstsection ex tended through said casing, said rod being angularly formedinterinec'liate of its length, a sleeve in said casing having an angularbore therethroi-igh, said intermediate portion of said rod being engagedin said bore and a nut carried by said second section for engagementwith the lower threaded extremity of said rod.-

In testimony whereof we affix our signatures, in presence of twowitnesses;
